One example is an antenna structure with a metamaterial having a flexible metamaterial layer, a two-dimensional antenna layer and a spacer layer. The flexible metamaterial layer has a metamaterial thickness allowing the metamaterial layer to be attached to a curved conducting surface of a vehicle. The metamaterial layer is formed with a two-dimensional array of elements having a passive magnetic property with the array of elements formed with elongated individual elements each having a top end and a bottom end. The elongated individual elements have curved outer surfaces between the top end and the bottom end. The two-dimensional antenna layer receives electromagnetic signals. The spacer layer is located between the metamaterial layer and the antenna layer separating the metamaterial layer and the antenna layer.

An unmanned aerial vehicle (UAV) includes a transceiver control device, and a dipole antenna electrically coupled to the transceiver control device and configured to communicate with a ground control station under a control of the transceiver control device. The dipole antenna includes a printed circuit board (PCB), a first oscillator spirally wound around an outer side of the PCB, and a second oscillator. The first oscillator and the second oscillator form a half-wave dipole antenna.

An antenna module and a transceiver that includes the antenna module which allow high-speed full-duplex communication. The antenna module has at least one antenna for transmitting and receiving electromagnetic radiation, at least one transmitter connection element and at least one receiver connection element for electrically connecting the antenna module to a transmitter circuit and a receiver circuit. The at least one transmitter connection element is in a transmitter section, the at least one receiver connection element is in a receiver section, and the at least one antenna is in an antenna section. The antenna section is between the at least one receiver section and the at least one transmitter section.

An antenna structure with multiple frequency capabilities applied to an electronic device includes frame body, first feed point, a first switch point, and second switch point. The frame body has at least one portion made of metal material and defines two gaps. The frame body between gaps form a first radiation portion. The first feed point from a source feeds current and signal to the first radiation portion. The first switch point and the second switch point are located at two ends of the frame body adjacent to the first gap. The first switch point and the second switch point are grounded through a switch circuit.

Disclosed are an antenna reflective net and an antenna reflective net mounting structure. Sliding slots are provided on side walls of the antenna reflective net mounting structure respectively. Protrusions of a base of the antenna reflective net slide into the sliding slots, and the size of the sliding slot is adapted to that of the protrusion. The protrusion is fixed in the sliding slot along a direction vertical to the sliding slot. A baffle block is provided at a distal end of the sliding slot. The baffle block restricts the protrusion from sliding along the direction of the distal end. Moreover, a limit part of an elastic pressing member of the antenna reflective net mounting structure restricts the protrusion from sliding along the direction of the entrance end of the sliding slot after the protrusion enters the sliding slot. Therefore, the antenna reflective net is easily mounted in the antenna reflective net mounting structure with high stability.

The present disclosure provides an electronic device with advanced antenna. The electronic device includes: a display screen; a metal frame surrounding a side edge of the display screen; and a connecting component disposed between the side edge of the display screen and a top end of the metal frame; wherein a height of the connecting component is larger than a preset height such that a portion of the side edge of the display screen not facing the metal frame has at least the preset height. Since the height of the connecting component is larger than the preset height such that the area of the portion of the side edge of the display screen which faces directly the metal frame may be smaller than a predetermined value. Thus, interruption between the display screen and the metal frame may be reduced or eliminated.
